Answer:
Yes, lines CD & AB are perpendicular
Step-by-step explanation:
AB slope: y = -12/8x + 7
CD slope: y = 6/9x - 6
Once the slopes are simplified:
AB: -3/2
CD: 2/3
Hope this helps!
Answer: 
Step-by-step explanation:
3/16= 12/64
a= 10/64
b=20/64
c=13/64
d=28/64
well, a is smaller, b is larger, c is larger, and d is larger, so we have B C D to work with. you can tell C is the smallest of the group B C D
C is the smallest that is still larger than 3/16
Answer:
#3) (4/3) pi r^3
(4/3) pi 4^3
(4/3) pi 64
volume = 21.333pi cm^3
#4) (4/3) pi r^3
(4/3) pi 14^3
(4/3) pi 2744
volume = 3658.666pi cm^3
Step-by-step explanation:

I'm not sure if there are any choices. But to find an ordered pair on the graph, you can plug any value in for x and solve for y.
For example, if we plug in a 0 for x, we get a 0 for y
y=4*0
Or if we plug in a 1 for x, we get a 4 for y
y=4*1
So two ordered pairs are (0,0) and (1,4)
